IMPROVEMENT IN CULTIVATORS.

To all lwhom t may concer-n:

Be it known that I, DUMMER PATTEE, of Ypsilanti, county ot' VVashtenaw, and State ot' Michigan, have invented a new and useful Improvement in Cultivators, which is described as follows, reference being had to the annexed drawing ofthe same, making part of this specification.

Figure l is a perspective view of the cultivator.

E is the main or upper beam, having a slit, 12, in the forward end thereof, into which is inserted a teuon on the upper end of the front sheth, A', through which a conecting-bolt,13, is passed, and in which slit is inserted a perforated segment-plate, F, called the regulator,77 let into the front sheth, A', and secured thereto by a bolt, 11, passing through it and the shethyhaving its upper end made curved and tapering where it passes through the slit 12, and provided with a segment row of holes, G, through which and a corresponding hole in the beam Ea confining-bolt, 15, is inserted for the purpose of changing the angle ot' inclination of the sheth A/ and ot' the other sheths.

A2 A3 AL are a first, second, and third pair of sheths, each pair being connected together by crosstimbers B C, and the several pairs connected together by train-irons G and connecting brace rods H. The beams B are mortised and tenoned into the sheths near the middle of the same. The beams C are connected tothe sheths by round tenons inserted into corresponding apertures in the sheths near their upper ends. The sheths are caused to move on these round tenons in changing their inclination. The beams E and I are fastened to the beams C C C. The upper beam, E, is bolted to the upper sides ot' the beams C by the bolts 11 11. The under beam, I, is bolted tothe under sides of the beams U C C. The shovels D are fastened to the lower ends of the sheths. The handles K K are fastened to the cross-timbers B C of therear pair of sheths by the bolts 20. The tongue L is attached to the several pairs of sheths by the iron straps or train-irons G, through which and the tongue and regulator is inserted a connecting-bolt,18, and through the sheths and train-irons the bolts 16.

'lhe straps of iron, G, are made iu pieces, lapped at their ends where they enter the mortises in the sheths, through which lapped ends and the sheths the bolts 16 are inserted. The brace-rods H are also made in separate pieces and lapped at their ends, and bolts passed through them into the round tenons ofthe timbers C. The sheths being thus connected to the main beam E by means ofthe combined train-irons G, regulator F, and bolts 15 and 18, will cause the several pairs of sheths A2 A3 A4 to assume the same angle of inclination that is imparted to the front sheth. A, and thus alter the depth of cultivation. The angle otl inclination ot' the sheth from a vertical line will be increased by raising the small end ot' the regulator F, and will be diminished by lowering it, the sheths moving in the arcs ot' circles described from the centers ofthe bolts 13`and 17 as the regulator is moved in the are cfa circle iu the slit 12.

The lower beam, I, is added for the purpose of extending the size ofthe cultivator by adding more pairs of sheths and shovels when required.

Angular braces may be added to the transverse beams, it' required, to give additional strength to the cultivator.

NVhat I claim as my invention, and desire to secure by Letters Patent, consists- In the manner ot' attaching and regulating the front sheth, and, in combination therewith, the manner of regulating the depth of cultivation, as above set forth.
